problems with the PXI7344 card

[Joerg]

I use the PXI 7344 card from NI and I have a problem, whit this card. If i initizialize this card under CVI it brings a warning, that i dont understand (CODE 4294897293). In MAX the CODE is -70003.
In my program ( I write it under CVI) the card start use of the engine, but I have make only configurations and tell him befor, that the engine doesnt start.
A friend tell me, that MAX makes changes, withou ma known, but I think that isn´t so... Wirte MAX the coniguration of my card also in the DAQ-file or write MAX the configuration into the memory of the card?
The card run in a system with a powerunit (MESA 1/1A-220/17-W-T-B5). can that device "knock out" my card?

The -70003 error possibly means that the 7344 is in power up reset state. I have attaced a sample program below that uses the flex_initialize_controller command if the board is in a power up reset state. You can test this by pressing the Reset button in MAX to simulate power rebooting the computer and put the board in a power up reset state. I have passed a NULL for the settings name and you can replace this with the name of your settings if you like. The settings must be loaded into MAX to use the settings name with the init command. Right click on the 7344 in MAX and select Initialization Settings >> Change Current Settings to see which settings are loaded.

The MESA power drive should not damage the 7344 or UMI if it is connected correctly. Please
see the 7344 and UMI user manuals for more detail about the circuitry.
